To all whom it may concern:

Be it known that I, JAMES P. HALL, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Molding Devices or ing plastic or other suitable material into bricks, building-blocks, or the like, andespecially for making concrete bricks or blocks from a mixture of cement and sand; and the invention relates more particularly to a novel device or machine to be used in the manufacture of concrete blocks of the angular type,

such. as areused in the construction of bay or bow windows and similar architectural structures or details.

This invention" has for one of its principal objects the production of a simple, cheap, and efiicient molding device for molding concrete angle-blocks and the like which can be'easily manipulated and by means of which the work to be performed can be accomplished with a great saving in time and labor and at a greatly-reduced expense. I

I A further object of this invention is to provide ,a molding device of the general character hereinafter .set forth by means of which concrete angle-blocks and the like of any desired degree ofangle may be formed or molded; and a still furtherobject of this invention isto provide a molding device 'for the purpose of forming or molding any angular de- 'gree of concrete angle-blocks or the like, the

said mold being provided with a minimum number of Working parts which may be readily set up or-adjusted to mold the said concrete angle-blocks or the like of any desired angular degree with a great saving of trouble and timein the operation and a conse uent saving of expense.

further important object of this invention is to provide a molding device of the character set forth which is readily adapted to form ormold What I will term for the urposes of this specification either outside forty-five-degree pitch and or inside concrete angle-blocks of anyde= sired angular degree.

Other objects of this invention notat this time more particularly mentioned will be clearly evident from the following detailed description of my present invention.

The invention consists, primarily, in the novel molding device or apparatus hereinafter set forth; and, furthermore, this inverttion consists in the various arrangementsan-d combinations of the devicesand parts, as well as in the details of the construction of the same, all of which will be'more fully described in the following specification and then finally embodied in the clauses of the claim, which are appended to and which form an essential part of this specification.

This invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a suitablyconstructed mold-box forming a art-of-the molding-machine or otherwise and illustrates my improved apparatus-for molding concrete angle-blocks or the like, arranged in its operativerelation to the saidmolding-box, .and further illustrating the novel ranged or adjusted to mold or form aconapparatus a-rcrete angle-block or the like provided with a 1 thirty-degree pitch and formlng whatisordinarily termed an outside angle-block. Fig. 2 is a side elevation of the apparatuseas illustrated in Fig. .1, one of the side Walls-of the mold-box being removed, lookingin the direction of the arrow X. Fig. 3-is aview similar to that shown in'Fi 2,; beingaside elevation of the novel-mo ding apparatus, but with the opposite side wall of the moldbox removed and lookingin the direction of l the arrow Y in said Fig.1. Fig. .4 1s a to or plan view such as isshown in Fig. 1, but il ustratin the novel molding apparatus arrange or adjusted to mold or form a concrete angle-block or the like provided with a forming anoutside angle-block. Fig. 5 is a to or plan view such as is shown in Fig. 1, buti lustratin the novel molding apparatus arranged or ad ust ed to mold or form a concrete angle-block or ,the like provided with a thirty-degree pitch and forming what is termed an inside angle-block. Fig. 6 is a view similar to that illustrated in Fig. 5, except that the: novel molding apparatus is arranged or adjusted to mold orform a concrete andinside angleblock or the like provided .with'a forty-fivedegree pitch.

Similar characters of reference are employed in the above-described views to indicate corresponding parts.

Referring now to the said drawings, the reference character 1 indicates any wellknown form of mold-box adapted to be used upon any type of molding-machine or otherwise, the said box comprising a pair of side walls 2 and a pair of end walls 3, under which is arranged a pallet-4,'all in the manner well known in the state of the art to which my present invention appertains.

To form the mold proper in which the concrete angle-block is to be produced, I have provided a removable mold-wall 5 of any suitable conformation, preferably in the shape of a hollow open-end box, as illustrated. This said mold-wall 5 normally is placed contiguous to or abuts against the inner face of one of the side Walls 2 of the moldbox 1 and is provided at the end with a pair of slotted and adjustable links or arms 6, the said arms 6 being held in any adjusted position by means of bolts 7. Secured upon the free ends of the slotted links or arms 6 by means of bolts 9 and thumb-nuts 10, so as to swing in a horizontal plane, is an arm, link, a

or extension-piece 11, having a concave or fork-shaped socket 12 upon its free end. The novel molding apparatus is further provided with a swinging mold-wall 13, also provided at one end with a pair of slotted and adjustable arms or links 14, the said arms or links 14 being held in any adjusted positions by means of bolts 15 and bein further provided at their free ends with ugs or cylindrical projections 17, which are adapted to engage with the concave or fork-shaped sockets 12, all for the purpose or providing a holding and joining means for holding the two side mold-walls 5 and 13 at any desired angle to each other. When the two side mold-walls 5 and 13 have been adjusted to the desired degree of the angle of the block of stone desired, the free end of the moldwall 13 is supposed to abut against the inner face of one of the end walls 3 of the mold-box 1. "The said mold-wall 13 has secured upon its free end by means of bolts and nuts 18 and hook-shaped lugs 19, (see dotted outline in Figs. 1 and 4 of the drawings,) adapted to hook into receiving-sockets arranged therefor in the said mold-plate 13, an end moldwall 20, extending at right anglesto the said mold-wall 13 and provided with reinforcingribs 21, arranged to give strength and rigidity to the sai end mold-wall 20. To form the opposite side mold-walls of the novel molding apparatus, there is provided a swinging mold-w all 22 and a mold-wall 23, adapted to be adjusted and arranged parallel, respectively, to the said mold-walls 13 and 5. For the purpose of providing a joining and holding device to secure the abutting ends of the said mold-walls 22 and 23 in their operative relation there is secured to the end of the mold-wall 23 a pair of oscillating arms or links 24, each of the said arms or links 24 being provided with a pair of parallel slots 25, and to the end of the mold-wall 22 there is secured a similar pair of oscillating arms or links 26, each being also provided with a pair of parallel slots 27. To hold the said arms or links 26 in rigid adjustment, there are provided bolts 28 and thumb-nuts 29. In order to further secure the said mold-wall 22 in its operative relation to the novel molding apparatus, the free end of the said mold-wall 22 is provided with a rod or other fastening means 30, to which is pivotally connected the one end of an arm 31, the other end of the said arm 31 being slidably secured, by means of a bolt and thumb-nut 32, to a slotted bracket 33, said slotted bracket 33 being provided at each end with downwardly-extending arms 34, which rest upon the pallet 4, which forms the bottom of the mold-box 1. The end of the said bracket 33, furthermore, abuts against one of the end walls 3 of the said mold-box 1, substantially as illustrated. To hold the mold-wall 23 in its proper and operating relation, there are provided a pair of extensible brackets, comprising a pair of slotted bracket arms or links 34, each being provided at one end with a downwardly-extending arm 35, preferably of dovetail conformation and adapted to be received and rigidly held in a pair of receiving-sockets 36. Slidably connected with the said slotted bracket arms or links 34 are other slotted bracket arms or links 37, also provided with downwardly-extending arms 38, the said arms 38 abutting against the inner face of one of the side walls 2 of the said mold-box 1. To hold the said extensible brackets, just described, in their rigid adjusted relation, suitably-arranged bolts and thumb-nuts 39 are employed, substantially as illustrated.

To complete the mold for forming or molding angle-blocks, there is provided an end mold-wall 40, held in its operative relation to the other mold-walls by means of a pair of extensible brackets comprising a pair of slotted bracket arms or links 41, each arm or link being provided at one end with a downwardly-extending arm 42, also preferably of dovetail conformation and adapted to be received and rigidly held in a pair of receiving-sockets 43. Slidably connected with the said slotted bracket arms or links 41 are slotted bracket arms or links 44, also provided with downwardly-extending arms 45, the said arms 45 abutting against one of the end walls 3 of the said mold-box 1. To hold the said extensible brackets just described in their rigid adjusted relations, suitable bolts and thumb-nuts 46 are employed.

The side mold-walls 23 and 5 are rigidly held against any backward or slipping movement by means of extensible brackets 47 of the same character or construction used to retain the above-described end mold-wall 4O in position, the respective extensible brackets 4C7 engaging, respectively, with the ends of said side mold-walls 23 and 5 by means of receiving-sockets 48', as clearly shown. A scale 19 may be arranged upon one of the side walls 2 of the said mold-box 1, with a corresponding gage indication or notch upon the side mold-wall 5 in order to indicate how far the said side mold-wall 5 must be moved to secure the different angular degrees of the mold-walls 13 and 22 and in consequence thereof of the mold proper.

Referring now more particularly to Figs. 5 and 6 of the drawings, I have illustrated my novel molding apparatus set up and adjusted to form or mold what I terin an inside angle-block. The apparatus used for the purpose consists of two side mold-walls 51 and 52, thesame being joined at their abutting ends by means of the toggle-hinge 53, similar to the joining and adjusting means used to connect the abutting ends of the side mold-walls 22 and 23, previously described. The side moldwall 51 is held in its rigid and adjusted position by means of a pair of extensible brackets 54, and the side moldwall 52 is held in like manner by means of the arm 55 and the slotted bracket 56, all of which is arranged and constructed in a manner similar to that already described and as will be clearly understood from an inspection of said Figs. 5 and 6 of the drawings. To form one end mold-wall, the plate 57 is placed against the end wall 2 of the mold-box 1, and to form the opposite end mold-wall the ribbed plate 58 is secured upon the side mold-wall 52 by means of the bolts and nuts 59 and the hook 60 in a similar manner to that previously described in connection with Figs. 1 to 4, inclusive. One of the side mold-walls is formed by the side wall 2 of the mold-box 1, as is evident from an inspection of Figs. 5 and 60f the drawings, and the other or swinging sidemold-wall is formed by the plate 61.

In order to support the plate 61 and adjust it at different angular degrees, I have provided a pair of extensible brackets comprising apair of slotted members or arms 62, pivotally arranged upon lugs 63 upon the said plate 61, and slidably connected with the said pair of slotted members or arms 62 is another pair of slotted members or arms 64, .each member or arm having a downwardlyextending arm 65, which abuts, respectively, against the end wall 3 and the side wall 2 of the said mold-box 1.

To secure the whole in its operative and adjusted relation, I have provided a locking.

means in the shape of the bolt and thumbnut 66, thus completing the apparatus for forming or molding concrete angle-blocks or the like of any desired angular degree.

From the foregoing description of my inmembers thereof are easily changed to other angles without the necessity of removing or substituting the various parts to secure the desired result, and, furthermore, to do away with any cumbersome arrangement of parts.
